Abstract : Noncircular conical and cylindrical shells, orthotropic and isotropic, are used in various branches of industrial construction: aircraft construction, ship construction, etc. The stability analysis of such shells, even in geometrically linear formulation, is a very complex problem. The solution of this problem with the aid of the presently known approximate analytic methods involves serious difficulties. It is probable that this is one of the reasons for the very small number of studies devoted to the stability of noncircular conical and cylindrical thin-wall shells. In the present paper this problem is solved by the differential-difference method, which is known in the literature as the method of 'straight lines' or strip method. (Author)
